Y. Application March 25, 1954, Serial No. 418,619 4 Claims. (Cl. 183-43) This invention relates generally to methods of cleansing gas and is directed particularly to devices for extracting entrained material from air and more especially devices of this character for use in association with clothes drying machines.

in clothes drying machines, vents are provided for the discharge of heated air after it has been blown through a compartment in which the damp clothes are agitated for the purpose of bringing such air into intimate contact therewith for the purpose of absorbing the moisture therefrom. The agitating action to which the clothes are subjected, frees a certain amount of lint particles which are picked up by the air stream and carried to and discharged through the vent. This air stream, after passing through the clothes compartment, also becomes heavily laden with moisture. In the majority of installations of such machines, the air vent of the machine opens directly into the room in which the machine is located and while a provision is made in such machines to catch the discharged lint, the moisture laden air is discharged directly into the room which results in greatly increasing the humidity of the room air and also in a great many cases causes moisture to condense and collect on the floor or upon objects adjacent to the machine. The lint catchers provided for clothes drying machines, particularly those intended for installation in homes for domestic use, are so constructed that they must be frequently removed and cleaned.

in the light of the foregoing, an object of the present invention is to provide a new and novel air delinting means which does not require periodic cleaning but which is of a disposable nature and can be readily removed from position with respect to the vent of the machine and be discarded and replaced by a new lint catcher.

Another object of the invention is to avoid the above stated objections associated with clothes drying machines by the provision of a new and novel means for not only catching and retaining the lint discharged from the machine vent, but for absorbing moisture from the discharged air.

A more specific object of the invention is to provide in a device of the character stated, a delinter of a novel construction and mounted for use in a new and novel manner whereby it can be easily and quickly removed and replaced by a new catcher as required.

A still further object of the invention is to provide in a device of the character stated an assemblage of cooperatively related units through which the lint and moisture laden air from a source of the character stated passes and has such lint and moisture removed therefrom before being discharged into the atmosphere.

The invention broadly contemplates the provision of a housing of suitable form which is adapted to be secured to a wall of a clothes drying machine over the air discharge vent thereof. Within this casing is mounted for easy removal and replacement, an air straining receptacle in which are retained lint particles carried by the air passing therethrough.

ice

The casing which is mounted upon the machine wall, is also provided with an outlet opening and interposed between the latter and the air straining receptacle are trays arranged in a staggered relation and carrying both mechanical and chemical means for absorbing the air which is caused to pass therethrough and also there around in its movement toward the casing outlet.

The casing is designed so that it may be easily opened without having to be removed from the wall of the drier machine to which it is attached so as to facilitate removal and replacement of any or all of the units contained therein. In one form of the invention, the lint gathering receptacle is in the form of an elongate bag of foraminous material having an inlet which is coupled with the vent of the drier machine, with novel means for detachably coupling opposite ends of the bag receptacle to oppositewalls of the casing while in another form of the inven tion there is provided a removable rack structure mounted in the casing and supporting a disposable receptacle having Walls of paperboard or other similar material, provided with openings or windows over which are secured a covering of foraminous material such as a woven fabric.

The chemical agent associated with the means for mechanically absorbing moisture from the air comprises ayers of granular silica gel alternating with layers of the mechanical absorbent which is preferably raw cotton. The chemical and mechanical agents, as stated, are preferred but other suitable agents may be employed. Preference is had for the granular silica gel in the device as this may be continuously regenerated for use by the application of heat as, for example, by passing heated air therethrough.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings with the understanding that the invention is not confined to a strict conformity with the showing of the drawings but may be changed or modified within the scope of the appended claims.

' Referring now more particularly to the drawings the numeral 10 generally designates, in Fig. l, a portion of a clothes drying machine cabinet of any type, either electrically heated or gas heated and the numerals 12 and 14 designate respectively portions of the top wall and one of the vertical walls through which the moist air carrying lint particles is discharged byway of theoutlet opening 16.

The lint and moist air outlet opening 16 may be circular as here illustrated or rectangular and in machines of this character there is conventionally provided some type ofreceptacle unit which is hung on the side wall 14 with apart covering the outlet opening 16 and apertured to have the lint carrying moist air pass therethrough into the receptacle. Such receptacles are detachable from the machine and the wall of the machine is customarily provided with apertures at a number of locations around the outlet opening, to receive mounting screws for supporting the lint catching receptacle in position. Such screw apertures may be utilized for mounting the present delinting device on the machine or any other suitable means may be provided for this purpose, the particular means for mounting the delinter of the present invention being immaterial.

The delinting device of the present invention is shown in two embodiments, one of which is illustrated in Figs. 1 to 7 inclusive, which embodiment will be specifically described first andthe'second embodiment is illustrated in Figs. 8 to 11 inclusive.

In the embodiment of the invention illustrated in Figs. 1 to 7 there is provided a housing which is generally designated 18 and which is, preferably of the rectangular form shown in Fig. 1. This housing comprises the back wall 29, side walls 21 and top wall 22, The front wall which is generally designated 23 ,comprises a removable door or cover for the opening 24 and is removably mount:

ed in position in the mannerjhereinafter set forth.

The back wall has formed therethrough, preferably adjacent to one side wall as here illns trated the opening 25 defined by the inwardly extending flangeor rim 26 and the housing when in position for use is secured against the wall 14 of the clothes drier machine with the opening 25 aligned with the opening 16 in the wall of the machine and is secured by any suitable means such, for example, as the screws 27 here illustrated.

Interposed between the wall 2110f the housing and the wall 14 of the drier machine is a thin-flatgasket While a gasket of this kind is preferred it is not an essential feature as the wall 20 of the housing may be secured directly against the wall of the machine as will be readily-apparent.

The bottom of the housing 18 has an air outlet opening 29 which is defined by the inwardly extendingback and sidewall flanges Slland 31 respectively which, in the construction of the housing of r netal, may form inturned bottom edge portionsof the back and sidewalls as willbe readily apparent and as shown in Fig. 4 the inturned flange portions 310i the side walls lie belowor againstthe underside of the back wall flange 30. l I

The front side of the bottom opening 29. is defined by the transversely cxtending flat base strip 32 which has formed integrally with it the upstanding sill strip 33;and

theends of the .base strip rest upon and aresecuredin a suitable manner to the side wall flangesjl asby spot welding at 34 or in any other suitableeway Likewisethe overlapping flanges and 31 may be spot wel d vas at fi qutsq nYotherdesired. mann rt a The material of the sill 33 is provided with an outer downturned portion 36, as best seen in Fig. 3, which downturned portion 36, as shown in Fig. 4, terminates at at its ends short of the side walls 21, the space between the end of the downturned portion 36 and the adjacent side wall 21 being designated 37.

The lower edge of the downturned sill portion 36 is continued in the upturned lip 38 which is spaced slightly from the portion 36 to form the groove or channel 39, along the bottom outer side of the sill.

Extending along the forward edge of the top Wall 22 is the downturned flange 40 defining the top of the door opening 24 and each side of this opening is defined by the inturned side wall flange 41, as shown .in Fig. 4, which at its top is in overlapping relation with the top flange 4t) and at the bottom is in overlapping relation with the adjacent sill 33 of the base strip 32 and these overlapped members are secured together by welding or in any other suitable manner, when the housing is formed of sheet metal or if itis formed of any other material suitable securing means between the overlapping parts may be provided.

Each of the side wall vertical flanges, or the flanges 41 bordering or defining the sides of the opening 24, has an outwardly disposed. laterally turned or directed lip 42 forming with; the adjacentflange 41 the laterally opening guide groove 43. These guide grooves 43 lie in the planeof the groove 39 which extends across the bottom of the opening 24.

The door or cover forming front wall comprises a sheetof material of suitabledimensions to completely cover the opening 24- and the side edges have portions folded or turned inwardly to. form a tongue 44 which is spaced from, the inner face of the wall body and is adaptedto have sliding engagement ina groove 43. These tongues are inserted into the grooves 43 bordering the sides of the opening 24, from the top and the bottomof the cover or door member which carries the inwardly and downward ly angled sill strip45 which, terminates at its ends inwardly slightly from the tongues 44. as shown in Fig. 12 and this sill strip is designed to enter .the sill groove 39 when thedoor is slid downwardlyintoclosing position.

The top edge of the door or cover body 23 is provided with a horizontally directed head flange 46 which, as shown in Fig. 3, engages upon the top wall 22 when the door or cover is in-closed positionand as here illustrated this head flange maybe providedby suitable bending of a portion of the top of the door body or it'may be provided as a separate piece of material. secured to the door body in any suitable manner.

The numeral, 50; generally designates anair straining and lint retaining receptacle which-receives the moist lint carrying air from the inlet 25,

The receptacleSO isofalength to extend substantially the entire distance between the side wallsv 21 of the-housingand is here shown as beingof rectangular cross'sectional design. a

This receptacle. Sllmay be defined as a-bag and is preferably formed throughout of a suitable woven fabric such as crinoline or the like and comprises the top and bottom walls SI-and 52,- the-front.and back walls 53 and 54 respectively and end walls 55.;

Theback wall 54 of the fabric, receptacle-or bag 50 is provided at one end with an opening 56 and positioned in this opening is an end of a coupling collar 57 and the edge portions of the material aroundthe opening are gathered sive tape or anyothersecuringmeans. This opening and the collar,57' are locatedwto; coincide with the annular.

flange 26 defining theopening 25 in the back wall. 20 of the ,housingand the; collar 57 is .of.an.inside diameter to snugly,frictionallymeceive .thegannular flange.;26, in the. manner illustrated in Fig. 3 when the receptaclev 50 :isv disa D posed horizontally in the top part of the housing with the end walls in closely spaced relation with the side walls 21 of the housing.

For the purpose of maintaining the receptacle horizontally in the top of the housing in the manner illustrated in Fig. 2 a rectangular flexible wire frame 59 is provided at each end of the receptacle, which frame is of approximately the same height and width as the end of the receptacle as shown in Fig. 6 and each of the four edges of the receptacle has secured thereto a frame retaining loop 60 through which the adjacent side of the frame passes as illustrated.

Cooperating with the mounting frames 59 are the mounting brackets 61, each of which is secured to theinner side of a side wall 21 and each bracket preferably comprises a strip 62 of suitable material having its upper and lower ends turned in to form the hooks 63. These hooks 63 are in opposing relation and each of the brackets 61 supports between the cooperating hooks 63 thereof, a frame 59, the bottom side of the frame engaging in the lower hook and the top side of the frame engaging under the top hook as is clearly illustrated in Fig. 2.

Disposed in vertically spaced relation in the housing between the lint catching receptacle 50 and the bottom outlet 29 are a number of moisture absorbing units, each of which is generally designated 64.

Each of the units 64 is supported upon a rectangular rack, the uppermost one of which, designated 65, is horizontally disposed between the side walls and against the back wall as shown in Figs. 2 and 3 and is of a width materially less than the width of the cabinet from front to rear. Beneath the horizontal rack 65 are two inclined racks 66 and 67, each of which is of substantially the same width as the rack 65 and the rack 66 is disposed adjacent to the front of the housing and inclined in the direction of its width rearwardly and downwardly, while the rack 67 is disposed at the back of the housing and inclined in the direction of its width forwardly and downwardly as shown in Fig. 3. While these racks may be made in any suitable manner to support the moisture absorbing units they are preferably constructed, for use in a housing of metal material, of light weight angle iron and each comprises the spaced longitudinal rails 68 and transverse end rails 69 connecting together the ends of the longitudinal rails. The end rails of the racks may be secured to the side walls 21 in any suitable manner as by welding or the like and the angles of the longitudinal and end rails are disposed so that one flange of each will be directed inwardly while the other flange stands upright to provide the necessary support and retaining means for the moisture absorbing unit.

The moisture absorbing units or containers 64 are of a length materially less than the Width of the housing between the side walls 21 as is clearly shown in Fig. 2 and the units, when placed in the housing upon their supporting racks, are set so that they will be in staggered relation or in overlapping relation at their inner ends as illustrated by setting the top unit with one end in close proximity to one side wall 21 and setting the next unit down with an end in close proximity to the opposite side wall and the third or lowermost unit directly beneath the top unit. Thus air flowing downwardly through the housing will not only pass through the units but will follow a tor tuous path by passing alternately from one side to the other around the ends of the units. Likewise, since the units are of a width less than the depth of the housing from the front to the back and are set in staggered relation with the top unit near the back, the second unit down near the front and the lowermost unit near the back as shown in Fig. 3 the air will also flow backwardly and forwardly between the front and back of the housing as it moves downwardly as will be clearly apparent.

Each of the filter units 64 comprises an elongate rectangular, open frame of shallow form or depth and com prising the parallel sides 70 connected by thetransverse ends 71.

The longitudinal edges of the sides 70 have inwardly extending flanges 72 therealong and the long edges of the ends have corresponding inwardly extending flanges 73 which join the flanges 72 of the sides so that the interior of the frame is in the form of a channel which is designated 74. I

The open sides of the absorbent unit frame are covered or closed by the fabric walls 75, the edges of which extend into the frame channel 74 and lie against the inner faces of the flanges 72 and 73 and interposed between these fabric walls are alternate layers 76 and 77 comprising re-' spectively absorbent cotton or other absorbent fibrous material and granular silica gel. Accordingly it will be seen that each of the units 64 carries within the frame structure thereof an air pervious pad consisting of outside layers of suitable fabric such as crinoline or the like and intermediate layers of fibrous material and moisture the under faces of the end and side flanges 31 and 30 respectively.

The screen 78 preferably comprises an elongate resilient frame which is generally designated 79 and comprises the side bars 80 and transverse end bars 81. While this frame may be made of any suitable material a light weight resilient wire is preferable because of lightness and because the resiliency makes it easy to put the screen in position with the use of the supporting means herein disclosed and hereinafter described.

- The screen proper comprises an envelope 82 formed of suitable woven material or fabric such as crinoline or the like in which the resilient frame 79 isfitted and the frame maintains the envelope in stretched condition. Thus there are provided by the making of the screen in the form of an envelope, the two fabric layers 83 which are spaced apart slightly by the thickness of the frame material.

A relatively simple and preferred means of holding the bottom opening screen in position comprises, as shown, the provision of tongues 84 carried by the back wall bottom flange 30 and the base strip 32.

The tongues 84 which are spaced from the elements to which they are attached, may be formed and mounted or attached in any desired manner but they are here shown as having been struck or cut from the flange and strip and pressed or offset outwardly so that they form an in--' tegral part of the strip or flange.

Fig. 4 shows the back flange 30 and the sill strip or base strip 32 at the front of the housing with the recesses 84 which result from the cutting out of the tongues there. from.

The portions of the tongues 84 which are spaced from the flange 30 and strip 32 are separated from such parts a distance to permit the screen unit 78 to be snugly in.- serted so that the screen will lie relatively tightly against the outer faces of the flanges 30 and 31 and the strip 32 and all air passing through the housing will be forced to pass through the bottom strainer screen as will be readily apparent, after it has entered and passed through the walls of thereceptacle 50, and through the strainer units 64.

In the embodiment of the invention thus far described it will be seen that when the receptacle 50 is to be removed for emptying and/ or replacement and also in order to remove the absorbent units 64 for regeneration preparatory to reuse, the housing is opened by sliding the remove able wall or door 23 upwardly and the receptacle 50 can then be readily taken out by disengaging the end frames 59 from the supporting brackets 61. The absorbent units,

out.

which rest in the racks, may then also be easilyv lifted" 7 In the second embodiment of the invention means is provided for supporting a disposable lint receiving recap-- t'acle; togetherwiththe absorbent units, upon aremovable rack structure within the housing. In this embodiment' thehousingis generally designated 85 and comprises the-back'wall 86; side walls 87 and low front wall 88.

The back wall 86 is provided with the air admission opening 89 and this opening is positioned adjacent to one side-ofthe-housing and is of proper area to-conform with theoutletopening-of the clothes drier cabinet, The wall 36 has secured to' the inners'ide a substantially U shaped upwardly opening frame 90; the bot-tom 90a of which'lieshorizontally just below theopening-89 while'th'e' sides 905 extend upwardly on-opposi'te sides of the opening to the top-edge of the back wall 86.-

The bottom of this housing 85 has an air outlet opening 91 corresponding to the opening 29 of the first embodimentand this opening is defined by the inwardly extending flanges 92" and 93' formed'respectively along the bottom edges of the backand front walls 86 and 88 and side wall flanges 94;

' The topof the housing 85 is covered or closed by the lid 95 which extendsv the full width and depth of the housing and is pivoted along its back edge asindicated at 96: to, the top edge ofthe back wall 86 for necessary opening and closing movements and this lid is defined by the downturned front and side flanges 98 -and'97 respectively as shown in Figs. 8 and 9'.

- In addition to the lid 95- there is the front door or cover 99which ishingedly connected along its bottom edge as indicated at 100 to the top edge of the low front wall 88 to swing on an axis-extending transversely of the housing as illustrated inbroken lines in Fig. 9 This front cover extends from the hinge 100' to the' topedges of the side walls and also extends the full width of the front of the housing between the side walls and when it isin closed position as shown in-Fig. 9 and the lid 95 is closed down when the front flange 97 ofthe lid overlaps the top edge of the cover 99' and thus secures it in closed position.

The bottomoutl'et-opening 91' for the housing 85 is covered by a strainer screen which isgenerally designated 101 and which is constructed in the same manner as screen 78 and is also supported imposition by tongues 102 whichmay be-of the same form as the tongues 84' or of any other :suitablecharacter. Accordingly it is not believed that a further description of this screen and the supporting: means therefor is required.

ln 'this second-embodiment of the invention the lint catching receptacle is of disposable nature and is supported upon a removable rack structure designed to be inexpensively fabricated from cardboard or similar cheap material.

Thedisposable lint catchingreceptacle is generally designa-ted 1 03 and the supporting rack structure therefor which: istmount'ed in the housing is generaliy'designated 104.

The rack. structure 104 comprises the two vertical side panels-105 which areconnectedtogether by an upper rackframe 106 and lower frames 107, 108 and 109'. These frames, except for the-fact that they are made of disposable'material such as cardboard or the-like, are of the sameiconstruction as the frames 65; 66 and 67hereinbefore: described' -and the-frames 107108 and109 arepositioned inath'e same manner asthe'hereinbefore described framesizto support on the'rack between the side panels 105? therfilter' units 64;

Theo-top fi'ameltl which supports the lint catching receptaole103, is horizontallydisposed' and is of the full widtlrof the panels 105"as clearly shown in Fig. 9 and 10.-

the top ends of the panels. 7

The lint catching receptacle 10s is in the form ofan elongate Box of paper, cardboard o'rtlie like, navi'ngtlte longitudinal top, bottom, front and back walls 111, 11 2, If?! and 1 14 respectively and the end walls 115'. V

The back wall 114 is'provided with the air inlet opening 116 which is of rectangular outline as clearly illustrated in Fig. ll and this is bordered on the outsideof the wall by the rectangular collar 117, the width and the height of which is materially less than the width andheight of the frame into which it is inserted when the lint catching receptacle is placed in position,- in the manner hereinafter set forth.

The top, bottom and'front walls of the receptacle 103 are provided with a plurality of window openings 118 and the inner surfaces of these Walls are covered by sheets or strips 119 of fabric material such as crinoline or the like which accordingly cover the window openings as illustrated.

As shown in Fig. 8' the lint catching receptacle 103 is of a length and width tofi't'sn'ugly within the area defined by the upstanding flanges of the frame 106 to rest upon the horizontal flanges of such frame and when the receptacle is so positioned and the rack 104 is set in the housing to rest upon the'bot'tom inturned flanges" 92, 93 and 94 the collar 117 will be positioned centrally in the U frame 90 and properly located to receive the moisture and lint conveying air entering the housing through the opening 89 from the clothes drying machine.

A seal is effected between the collar 117 and the bottomand-sides of the frame 90 by encircling the collar 117 with suitable fibrous material such as cotton wool, asbestos fiber or the like as indicated at 120.

It will be seen from the forc'going'that the moisture absorbing units 64 may first be placed upon their respective supporting rack frames, while the rack structure is outside the housing after which by'fully opening the lid and the front door 99 the rack 104' can be set into thehousing. Following this the lint receiving receptacle 103, after having the collar 117 wrapped in the manner stated, can be inserted downwardly through the top of the housing to its resting position on the frame 106, which. operation will at the same time cause the wrapped collar 117' to enter the upwardly opening frame 90.

These operations of removing and replacing the lint catching receptacles either through the front opening of the housing constructed in accordance with the first described embodiment or by lifting them in and out as a unit with the rack 104, may be easily accomplished without having to remove the housing from the wall 14 of the clothes drying machine.

In the second described embodiment the rack structure104 and the receptacle 103 are designed, as hereinbefore stated, to be fabricated from inexpensive material so thattthese parts can be disposed of if and when desired.

From the foregoing description it will be apparent that there is provided by the present invention a new and efficient means for delinting the air discharged from the clothes drying machine and for elfectivelyremoving the moisture therefrom so that the present necessity for removing a lint catcher and cleaning out the same by handiseliminatcd and where the clothes drying-machine is installed in a room or in a basement the surrounding air is not highly humidified as is the case with conventional driers where no provision is made for removing the moisture from the discharged air. This isa very' desirable feature at all times and particularly during the summer when the addition of humidity to the Warm air greatly increases the discomfort occasioned by the heat.
